Abstract: The Beishan pit exploration facilities in Gansu province is the landmark facilities of the research and construction phase of the high-level radioactive waster geological disposal engineering in our country.Based on the smooth blasting method，the blasting parameters of the Beishan pit exploration facilities have been designed，which is much more suitable to this project.Furthermore,the smooth blasting effects is analyzed under the different kinds of blasting parameters (spacing of peripheral holes),the scientific of smooth blasting parameters is verified.In advance.It should be noticed that,blasting method includes numerous blasting parameters，which interaction each other.Those blasting parameters obtained just on the spacing of peripheral holes,and the results and theoretical knowledge could be applied to the blasting and excavation of the deep geo-engineering and the high-level radioactive waster geological disposal.

Key words: Smooth blasting, Blasting theory, Blasting parameters, Pit exploration facilities
